The invention is fully disclosed. The following discussion suppliesadditional details associated with various embodiments of the invention.

In one embodiment, there is provided a function on a display unit or asprojected onto or through a surface which functions as a display unit, asingular object or plurality of objects (i.e., gaze point object or gazepoint objects), at a fixed point or bounded by a region or moving orrotating in two or three-dimensional space, realized at a distance fromthe user as part of a horizon or above a ground plane in a virtualrepresentation or simulacrum of the earth's sky. The projection of thevirtual sky may be equirectangular or panoramic or wide, upon which theuser gazes while their full field of view is enveloped by anever-changing transition of color gradation and light intensityoccurring at an increased speed. This transformation imitates thevariance in sky colors and their brightness during the passage of atwenty-four-hour day-night cycle. In one embodiment, this occurs withoutgraphical representations of planetary bodies (e.g., sun, moon, stars)present in the virtual sky.

The user experiences in a full field of view the constantly developingappearance of the earth's sky between sunrise and sunset and nighttime,realized in a virtual environment and across a compressed time period,rather than in real time. The compressed time is from an hour to mereseconds or other user-definable duration. In one embodiment, thecompressed time period is six minutes or less. In so doing, theInvention mimics the transforming color temperature of the earth's skyfrom OK to <7000K and solar irradiance from 0 w/m² to 1250 w/m², and theeffects of diffuse sky radiation such as Rayleigh and Ramen scatteringof sunlight, and meteorological changes such as temperature inversion,that turn the sky a multitude of colors over a twenty-four hour periodwith shifting lambency: from the blue colors of the daytime and twilightsky, to the burning red and yellow hues of dusk, as well as otheroptical phenomena such as green flashes.

By exposing the user to the dynamic color palette of a virtual sky withan accelerated day-night cycle, the disclosed technology coordinateschronosynchronization throughout body systems, resetting to theirinitial temporal state physiological functions affected by dysregulationand/or asynchronism: autonomous oscillations, known as circadianrhythms, in and relative to the suprachiasmatic nucleus of thehypothalamus and the body's network of organ, tissue, and cells whichprevent or alleviate the effects of autonomic dysfunction, acute fatigueand myalgic encephalomyelitis (chronic fatigue), anxiety and depression.

The process of establishing chronosynchronization in the user isindependent of environment setting and requires that the userparticipate in an activity which focusses gaze at a fixed point,relative to the user, while the transition of hues and brightness fills,envelops or occurs in their field-of-view. The transition has a variablegraphical appearance which triggers the user's cognitive recognition ofnight and day or other light patterns affecting cognitive perception.The location, shape or appearance, size, position, orientation and, ifmoving on a trajectory, speed of transit or rotation and direction ofthe object(s), may be varied, whether by the user or dynamically.

The virtual sky can be displayed in a standalone environment or, whereembedded, can dynamically interact with the flow of an environment, suchas in a game program or the real world. The user can voluntarily summonthe virtual sky or be prompted to do so if a computer program determinesthat the user needs to reset the autonomous oscillations of the body,whether as according to a predetermined condition or a conditiongenerated by the computer or program itself. User interaction with thevirtual sky may include button, gesture or voice commands.

A variation of the technology is its ability to establishchronosynchronization using a day-night cycle relative to the user'slatitude and/or longitude, whereupon the color gradation and lightintensity will reflect the real-world sky at the user's geographiclocation.

A variation of the technology is its ability to establishchronosynchronization by imitating a day-night cycle relative to that ofanother planetary object and its geostationary or geosynchronous orbit.Color temperature and solar irradiance, or other optical phenomena, inthe real-world sky on another planetary object may be sampled orcalculated using, including but not limited to, photographs and videocaptured by an autonomous exploration vehicle and subsequentlyreproduced in the virtual sky.

An embodiment of the technology is a display to the user when a portablehead-mounted electronic device or apparatus is worn on the user's head,such as a virtual reality or augmented reality or mixed realityhead-mounted device, or other such device or apparatus which may or maynot retain a portable electronic device as a method of operation andcommunication, but which otherwise acts as a method of display to theuser.

Another embodiment of the technology is its representation not only on asingular display surface but also across multiple display surfaces suchas a computer, portable display screen, folding device with or withoutflexible display screen, mobile phone, watch, seatback or wall-mounteddisplay, augmented reality head-up display, digital mirror device, orholographic display. Irrespective of the proximity from the user, theuser may hold, place or situate in front of themselves a singulardisplay or multiple displays while looking at and interacting with thevirtual sky. Interactions with the virtual sky may include by capacitivetouch, eye tracking or any other method of interaction determined by theuser and/or software and/or device, which either partially or in itsentirety can span multiple screens and/or devices and is platformagnostic.

An embodiment of the technology is its representation in a spacecraft,space station and/or other orbital station and/or permanentinfrastructure sustaining human operations on another planet and/orother astronomical body, aircraft and/or motor vehicle and/or trainand/or tram and/or boat, not only on a singular display surface but alsoacross multiple display surfaces such as a computer, portable displayscreen, seatback or wall-mounted display, augmented reality head-updisplay, digital mirror device or holographic display.

An embodiment of the technology is its representation in anyenvironment, such as a bedroom, clinic or office, the interior of avehicle, or an art gallery installation space, wherein a single lightingdevice or multiple lighting devices, whether smart lighting devices ornot, and whether controlled by a smart lighting control system or not,emit(s) or project(s) a color temperature and light transition in thesurrounding area whereupon a person's gaze may be fixed at any point,whether directed to or not.

The disclosed technology coordinates a process of chronosynchronizationin a person's circadian system by resetting circadian rhythms to theirdefault state throughout the network of organ, tissue, cells andfree-living, nonphotosynthetic prokaryotes in the human body. Thedisclosed technology, therefore, facilitates precise temporalorganization of cellular processes through the stabilization of cellularclocks, further regulating stochastic timing in gene expression as partof the overall circadian system.

It is the way of all living things that life is born, matures, ages anddies. Humans are temporal by our very nature, having associated themeasurement of time with a twenty-four hour day, punctuated by periodsof light and darkness of variable length, with the revolution of theearth as it, in turn, revolves around the sun. Consequently, our bodiesuse time to keep us alive and functioning for every cell in the bodypossesses a circadian clock. As these cells organize into tissues, whichfurther organize into organs, they all tell time. There is a rate,rhythm, sequence and timing to everything which has to be coordinated,and this function is performed by the suprachiasmatic nucleus of thehypothalamus.

The suprachiasmatic nucleus coordinates organs, tissues and cells in atop down manner, synchronizing everything a human being does thatinvolves time, just as the cells, tissues and organs inform thesuprachiasmatic nucleus about what needs to be coordinated. At the sametime varied rhythms and frequencies in the body must be independentlyrun by the organs, such as a person's heartbeat and differences insystolic and diastolic pressure, while still fitting in the overallscheme of the suprachiasmatic nucleus's coordination. These rhythms areaffected primarily by light and dark cycles, but also by moreindependently controlled variables such as sleep length, sleep timing,artificial light, eating times, etc.

As society industrialized in the Victorian age and took control of theenvironment, so people learned to abolish the dark with various forms ofartificial light which impeded their sleep by entraining the circadiansystem to both delay the onset of sleep and shorten its duration. Peoplelet factors other than the appearance of dawn wake them to go to workand early-night moonlight to send them to their slumber and now performtheir work around the clock instead of during traditional daylighthours.

These environmental factors and activities, among many others, throw offcircadian rhythms in the body which affect people in profound ways. Itis universally accepted that these circadian rhythm disturbancesinterfere with sleep, but they also affect everything in our bodies thatinvolves timing, sequencing, rhythms, oscillations and rates, i.e.everything that keeps a person alive and functioning. Injuries,illnesses, psychological trauma and aging all affect the complex networkof circadian rhythms, thereby causing dysfunction, dysregulation orasynchronism. As this begins, so inflammation and cellular breakdownoccurs, thus resulting in serious illnesses such as dysautonomia,cancer, diseases of aging, depression, seasonal affective disorder,endocrine disease, acute fatigue and myalgic encephalomyelitis (chronicfatigue), heart disease, addiction, sleep disturbance and cognitiveproblem solving deficits, alongside a broad set of additional symptoms.It is the circadian system's ability to coordinate all of the body'stiming mechanisms that determines when people start to malfunction, downto the cellular level. As this system breaks down and stops functioning,we die, whether from a catastrophic injury or a slow, lingering illness.Regardless of the cause, when the circadian rhythm system ceases tofunction, life can no longer be supported.

The disclosed technology addresses the effects of sleep disorders byexposing the user to a transition of color temperature and lightintensity that reproduces or pertains to the time period between theonset of dusk and the emergence of dawn in a day-night cycle. Thedisclosed technology should be used during hours of darkness toestablish chronosynchronization, prior to or after a waking, duringwhich time the user may experience disorders of: initiating andmaintaining sleep, excessive somnolence, a sleep-wake scheduledisruption, and other dysfunctions associated with sleep, sleep stages,or partial arousals including parasomnias. People who experiencesleep-wake schedule disruptions, owing to an irregular or compressedsleep schedule in response to their working environment, will benefitfrom chronosynchronization being established by the disclosedtechnology, including but not limited to: night-shift workers, militarypersonnel and defense contractors, professional athletes, long-haulgoods transportation drivers, miners, and scientists and researchersworking in extreme conditions such as at the earth's poles.

The disclosed technology further addresses the effects of asynchronismin the circadian system as a direct consequence of jet or travel lag andspace flight, orbit and exploration. In jet or travel lag, asynchronismin the circadian system occurs as the result of a person being exposedto temporary shifts in the day-night cycle while traveling across timezones. Transient disruption to sleep architecture causes phasemisalignments of the sleep-wake cycle which are addressed by use of thedisclosed technology to establish chronosynchronization at thegeographic point of departure and subsequent point of arrival. In spacetravel, orbit and exploration, asynchronism occurs in the circadiansystem as people enter into a different day-night cycle to earth. Be itin space flight or while stationary or geostationary, the circadiansystem is subjected to the rotation of a planetary object. On theinternational space station, astronauts experience an entire day-nightcycle rotating around the earth once every ninety minutes. Space lag is,therefore, extreme, causing substantive disruption to sleeparchitecture. To address this issue, it is critical that a day-nightstructure be maintained in space which mirrors that on earth. Theinvention does this by establishing chronosynchronization relative toearth's day-night cycle. However, the invention can also display aday-night cycle relative to that of another planetary object, where thisdifferent time period may be deemed necessary for chronosynchronizationto be achieved in space flight towards the planetary object, or upon theplanetary surface.

The circadian system in the human body will inevitably fail. Itslong-lasting stability is remarkable, however it will break down withaging, injury, chronic illness and trauma. The circadian system isdependent upon external factors affecting the hypothalamus and thecellular clocks. In a virtual or projected environment these variablescan be taken into account and coordinated in a significantly compressedtimespan. Conversely, real world attempts to reset the cellular clockswithin the circadian system are fraught with failure, with acceptedclinical medical practice being: (1) light and dark exposure, includingspecific bands of light with or without cognitive behavioral therapy;(2) pharmaceutical intervention; (3) the rotation of a person's sleeppatterns, such that they time their sleep schedule three hours ahead ona daily basis until arriving at a desired hour some seven to eight dayslater; and (4) a combination of the above mentioned light and darkexposure, feeding and fasting behavior and physical exercise, whichrequires that the individual make significant lifestyle changes. Unlikethese minimally effective approaches, that can take years to seeresults, embodiments of the invention take minutes to perform a reset ofthe circadian system, which can be repeated at timed intervals with noimpact on lifestyle.

Further, in virtual, augmented or mixed reality, time, timing, sequence,rate, rhythm, oscillation, brain wave entrainment including alpha, beta,delta, gamma, theta and other waves, light, dark, color, latitude,longitude, season, can all be configured and brought to bear bothconcurrently and at the user's convenience. In normal reality, theprecision of this approach would not be possible. The goal, therefore,is to instruct the circadian system to reset itself at thesuprachiasmatic nucleus and for that reset to then be channeled amongthe cellular clocks. As genes turn other genes on and off, so thecircadian system makes granular adjustments to a person's innate senseof time that can have a lasting and cumulative effect. Instead of takingdays to years to attempt to reset, this can be done in as little as aminute and as long as six minutes. Further, as the circadian clock inevery cell is adjustable by systemic and local machinations of thesympathetic (systemic) and parasympathetic (local) nervous systems,demonstrable outputs can be seen from those automatic activities in thehuman body which do not require conscious intervention; those which aresequenced and timed by the circadian rhythms that determine cortisolrelease sequencing, dopamine release amount, location sequencing, lightto dark sequencing, and blood brain barrier sequencing.

Once adjustments are made at genetic levels, so instruction sets aresent out within the human body to modify the circadian system. Thisinvolves adjustment at the suprachiasmatic nucleus, instructingentrainment downwards as the cellular clocks further instructentrainment upwards to it. In concert with daily resets at morning andbedtime, in our modern environments that inhibit natural circadianrhythms which are set at dawn and dusk, the changes should not onlyoccur but should last. By resetting the overall circadian system we mayslow down the effect of time on our bodies. Indeed, it is not thepassage of time that creates problems, rather it is asynchronism ofthese autonomous oscillations that does; it is the failure to lockcircadian rhythms to the cellular clocks that causes inflammation whichsubsequently ages us.

Resetting the circadian system at rise and bedtime should establish astable entrainment that does not drift in time as much. When it does,use of the disclosed technology should reset the asynchrony, therebypreventing or inhibiting further temporal drift which will cause morecircadian clock disruptions over time. Since each organ relies upon itsspecific use of time, that must remain coordinated by light and darkperiods being received by the retina and passed to the suprachiasmaticnucleus, sequential daily resets should also be soothing and relaxing,imparting energy during the day and restful sleep at night, whilefurther maintaining good melatonin levels and fighting off majorillnesses.

A good illustration of circadian entrainment is the sequencing people doduring the day. We tend to perform many steps in a specific order to getthrough the day. If that sequencing is disrupted, however, we tend toexperience mild discomfort which is only corrected by putting subsequentsteps back in order. If that discomfort is allowed to build, anxietydevelops. Therefore, coordinating the sequences with the driftingcircadian system restores well-being. Resetting the circadian systemregularly should decrease anxiety substantively.

Since resetting the circadian rhythm system is so difficult in real timein the real world, no one has ever really had the chance to study thiseffect in people over time. Using the disclosed technology allows us todo so simply, quickly, and effectively. Further, developing a routine ofusing the disclosed technology upon awakening and going to sleep shouldafford people a great hedge against diseases of aging and slow downaging itself. Clearly, the circadian system has direct effects uponepigenetics and, if used regularly, the invention could positively alterthe epigenome.

The virtual sky can be varied or altered while accomplishing itsobjective as the activity involved is unrelated to the end result. Theuser can be instructed to perform actions that have little to do withthe end result or otherwise perform actions without being aware of theend result. There is a wide scope to vary the representation of thetechnology by changing color, intensity, texture, dimension, shape,sound, flavor and smell. It is also not necessary to represent the colortemperature and light intensity transition as mimicking the day-nightcycle. In addition, sound alone may be used to assist with some aspectsof entrainment of the circadian system, affording visually-impairedusers access to the invention.

Different methods of directing user attention or engagement and activitycan also be applied to the invention, whether dynamically or not, byvarying the appearance of the singular object or plurality of objects aswell as the point of engagement and the method of engagement. Userengagement activities can include pointing, gesturing and glancing, anduser instruction can be varied (e.g. “look ahead and shoot the ball.”).Embodiments of the invention can be accessed through a variety ofsoftware or hardware devices and be augmented by a range of observationsthrough the application of machine learning and artificial intelligence,as well as neural interfacing and processing tools.

A variation of the technology is the ability to scale or transform asingular object or plurality of objects at a fixed point upon which theuser gazes by numerically increasing in size the object(s) height, widthand depth dimensions over a timed duration and numerically decreasing insize the object(s) height, width and depth dimensions over a furthertimed duration. Whereupon a plurality of objects are visible to theuser, the dimensions of these individual objects may be numericallyaugmented or diminished in size independently of each other and thetimed duration of the scaling of their dimensions may also occurindependently. The singular object or plurality of objects may berotated at any angle or velocity. The process of resizing a singularobject or plurality of objects over timed durations gives rise to asynesthetic experience. By replacing an auditory rhythm that the userhears by means of an auditory input in the region of 0.01 Hz up to 1kHz, at an optimal range of 0.01-400 Hz, with a visual rhythm receivedand transmitted by the user's visual cortex, an oscillation is set upbetween the Default Mode Network (DMN) and Frontoinsula Network (FIN)brain regions that establishes an entrainment of these two brainsuper-networks. A variation of the invention is the ability to scale ortransform a singular object or plurality of objects at a fixed pointupon which the user gazes by changing the form of the singular object orplurality of objects over a timed duration. The singular object orplurality of objects may also be transformed to their original form overan additional timed duration. The singular object or plurality ofobjects may be rotated at any angle or velocity.

Embodiments of the invention replace one sensation (e.g., visual) foranother (e.g., auditory or vibratory). Other embodiments augment onesensation with another. In the visual realm, it is known that visualpatterns at or around 17 Hz risk visually induced seizures. Accordingly,embodiments of the invention avoid visualizations proximate to thisvalue. Thus, for example, an auditory input or a vibratory input may betransformed into a visual input that oscillates between 0.01 Hz to 12Hz. As another example, an auditory input or a vibratory input may betransformed into a visual input that oscillates above 24 Hz. In anotherembodiment, a visual input is transformed into or augmented with anauditory input or a vibratory input in the range of 0.01 Hz to 400 Hz.

As previously discussed, an embodiment of the invention includes a gazepoint in the digital space, as shown in FIGS. 3A-3D. Cyclical sizechanges of the gaze point may be used for facilitating cognitiveclarity. In particular, the virtual sky projection module 142 augmentsthe operations of FIG. 2 to include cyclical size changes of a gazepoint, as outlined below.

A gaze point is formed in the digital space. The gaze point experiencessize changes between a minimum size and a maximum size during a gazepoint size change cycle, where the gaze point size change cycle isrepeated throughout the time period of the user experience. In oneembodiment, the minimum size is a unit size and the maximum size istwelve times the unit size. In another embodiment, the maximum size isfour times the unit size. In one embodiment, the unit size isapproximately 2 mm in the digital space.

In certain embodiments, the gaze point size change cycle is between tenand thirty seconds. In one embodiment, the gaze point size change cycleis twenty seconds. As shown in FIGS. 3A-3D, the gaze point changesvisibility characteristics depending upon current color palettetransitions in the virtual sky in the digital space. In one embodiment,the gaze point cyclical size changes are coordinated with visual orvibratory phenomena at approximately 0.05 Hz.

It is well established that cognitive function is on a continuum.Variations in cognitive function occur because of illness, natural agingprocesses, developmental phases of life and daily vicissitudes. Normalcognitive function is dependent on in-phase circadian rhythms. However,when these circadian rhythms fall out-of-phase, individuals willexperience symptoms of cognitive dysfunction known as “brain fog.” Thereis a need to facilitate cognitive clarity to overcome such brain fog.

Normal function of the circadian rhythm is critical to managing theBlood Brain Barrier. During a day period of a day-night cycle, lightexposure determines molecular ingress into the brain by opening theBlood Brain Barrier to transport substances from the body to the brainvia the unique capillary system of the central nervous system. Thisallows for brain nutrition and energy consumption. During a night periodof a day-night cycle, and in direct contrast to a day period, thecircadian rhythm reverses the flow of substances to the body from thebrain, thereby removing residual and retained biological waste material,the consequence of normal brain metabolism and a major contributor tocognitive defects. To stabilize cognitive dysfunction, it is necessaryto create a delta wave stimulus in the periventricular area thatactivates the glymphatic system to reverse the blood-brain barrier.

The user experiences color palette transitions in a virtual sky for anexperience period (e.g., six minutes or less). The user enters thevirtual experience at their current time and completes a twenty-fourhour day-night cycle within the experience period. The color palettetransitions in the experience period are as described above, such thatthe experience incorporates color palette transitions from dawn todaytime to dusk to night, as well as color temperature and intensitychanges.

The user gazes at a fixed point object above the horizon that oscillatesin a sinusoidal pattern (e.g., at 0.05 Hz per cycle of twenty seconds).In one embodiment, the size and perspective of the fixed point objectincreases for half of the duration of the sinusoidal waveform, e.g., 10seconds, and then decreases in size and perspective for the remaininghalf duration of the sinusoidal waveform, e.g., 10 seconds. This givesthe user the impression that the fixed point object is expanding intothe foreground and receding into the distance every cycle. Thisoscillation remains constant throughout the experience period.

The invention stabilizes and manages the in-phase circadian rhythm topromote deep-delta sleep and reversal of the Blood Brain Barrier,thereby optimizing appropriate performance of removal of waste materialfrom the brain and central nervous system. The invention utilizes thecircadian rhythm day-night cycle mimicking a 24-hour period in acollapsed experience period of six minutes or less. Embodiments of theinvention use synesthetic substitutions, whether vibratory, visual, orauditory, to create synergistic responses that manage the in-phasecircadian rhythm. By replacing an electrical input at 0.05 Hz in thebrain with a visual rhythm of 0.05 Hz received and transmitted by theuser's visual cortex, an oscillation is set up that instructs the BloodBrain Barrier to form channels into which the ventricles of the brainempty cerebral spinal fluid. The fluid rushes through the channels atsixteen times the normal velocity of cerebral spinal fluid in the brain.The pressure created by the velocity of cerebral spinal fluid in thesechannels consequently forces waste material, carried with it from therest of the brain, out into the body's systemic circulation through thepervasive tight junctions of the brain's capillary walls.

If a person's circadian rhythm is in-phase, the waste material ejectionprocess utilizing cerebral spinal fluid normally takes place duringdeep-delta sleep on a daily basis. When this is not the case, wasteremoval is inefficient and contributes to cognitive deficitscolloquially identified as brain fog.
